Última Environmental Benefits from Reduced Pesticide Use and Returns to Research: An Application to the U.S. Cotton Industry AgEcon Sande, Doris N.; Mullen, Jeffrey D.; Matekole, Augustus N.. Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”. The result is resistance to insecticides, high control costs and unacceptable levels of chemical insecticides in the environment. Concerns about the environmental and human health effects from pesticide use thus need to be modeled in evaluation studies.

Ano: 2009 URL: http://purl.umn.edu/49519 Best Management Practices: How Economical is it in Southern Agricultural Systems? AgEcon Matekole, Augustus N.; Westra, John V.; Appelboom, Timothy W.. Conventional drainage systems tend to aggravate runoff and nutrient leaching problems on farms especially during the off-season. This study uses a biophysical economic model to identify, evaluate and determine multifunctional benefits of implementing and establishing nitrogen rate fertilizer application and conservation tillage practices as best management practices (BMPs) in the lower Mississippi River Basin (MRB). Simulation results showed that agricultural producers generally preferred no tillage to conventional tillage in reducing nutrient runoffs from fields because of higher net revenue per acre. Finally, given nitrogen runoff restrictions, farmers reduced crop acreage and nitrogen fertilizer application rates to help minimize losses.
